I queried this issue, here's what mines saying!!Couldn't control gantry position. Check for jamming or disconnected cable. I can't find anything wrong. I just bought this table about a week ago, and very naive to functions, please help.

Ity is VERY important to remember to NOT manually push the gantry or carriage too quickly on the PlasmaCam, Samson 510 and GoTorch machines. If you need to move anything, be p-a-t-i-e-n-t and do it slowly. These problems often crop up after quickly shoving the gantry or carriage out of your way.
